Perhaps better as

#define _FP_FRAC_CLZ_8(R, X)                   \
  do                                           \
    {                                          \
      int fs8_i;                               \
      for (fs8_i = 7; fs8_i > 0; fs8_i--)      \
        if (X##_f[fs8_i])                      \
          break;                               \
      __FP_CLZ ((R), X##_f[fs8_i]);            \
      (R) += _FP_W_TYPE_SIZE * (7 - fs8_i);    \
    }                                          \
  while (0)
